To all whom; may concern:

Be it known that I, LEON NAoAx'r, of Liege, in the Kingdom of Belgium, gunmakcr, have invented new and useful Improvements in Breech-Loading Fire-Arms, of which the following is a specification.

The invention consists ot' a new arrange ment of mechanism whereby the breech ofthe arm.,is firmly closed, the handling made rapid and simple, the dismounting and remounting easily performed, and without any other tool than a plain turn-screw with a single blade.

The breech mechanism comprises a breechbox containing an obturator pivoted upon a transverse axis. A lever pivoting upon another axis takes under the obtnrator, which it maintains pressed immovably against the faced end of the barrel. In the obtu 1ator is placed a striker, pivoting upon a transverse axis placed toward the middle of its length. The head of the striker' carries a -rear shoulder. In the obturator, where the striker is placed, is a stop, against vwhich the shoulder of the striker abuts. This arrangement limits the backward movement of ,the striker in the obturator, and prevents it from leaving it even in the case of aviolent retrograde effort. Inthe body of the lever, or at its side, is placed a hammer, intended to act on the striker. It may have the same axis as the lever, or a special one. This hammer, being carried by the lever, cannot reach the striker if the lever has not completely effected the closing by taking entirely under the obturator. A cartridgeextractor is worked by the obtnrator. It may have the sameaxis as the latter, or a special one. The arms ot the extractor may be furnished with wings (ailettes) entering recesses formed in the faced end of the barrel. The arms of the extractor are thus held very firmly, and cannot be displacedv or deformed by the effort of the explosion, even if the breech end ofthe barrel is isolated, instead of being held in a breech-box. The trigger-guard carries the trigger and the mainspring, and may also receive other pieces of the mechanism. It is fixed at one end to the lower tail of the box by means of a screw, upon which it pivots. The body of the trigger-guard is held in place by a screw in the inside of the box. This arrangement allows of withdrawing the trigger-guard,

as well as the pieces of mechanism attached to it, without dismounting the stock. This trigger-guard constitutes, also, a lever, serving for dismounting and mounting the niainspiing without the help of a special instrument.

Figure 1 shows the mechanism closed, with the hammer down. `The head of the hammer rests against the striker, the point of which projects from the obturator. Fig. 2 shows the mechanism closed, but with the hammer cocked, ready for firing. Fig. 3 shows the mechanism open, with the extractor throwing the cartridge out of the chamber. The point ofthe striker has been withdrawn into the obturator. This figure also shows the dismonnting of the trigger-guard and the pieces connected with it.

The wings H2 of the extractor are lodged in the recesses H3 of the barrel.

In order to open the mechanism, the tail of IOO 'l the lever G is pushed forward. The head Cl then turned over backward.

of the latter retires from under the obturator, which is thus disengaged. The tail of the lever then meets the lower arm,Y E2, of the striker, which retires into the obturator. The object of this movement is to cause the point of the striker to retire automatically into the obturator. Immediately after, the tail of the lever pushes forward thelower part, A, of the obturator, of which the upper portion, A4, is

By this movement the faced end of the barrel is uncovered. and the obturator, transmitting to the extractor the impulse that it has itselfreceived from the lever, forces the extractor to throw the cartridge-case` out of the chamber. At the same time the lever has fully cocked the hammer.

The hammer can be also cocked and uncocked by its crest independently of the lever. The hammer has also a notch for half-cooking. In order to reclose the mechanism, the tail of the lever (or the foot ofthe obturator) is moved backward. The head of the latter, sliding against the upper and hinder part, A4, ofthe ob turator, pushes the latter against the faced end of the barrel. Arrived at this point the head ofthe lever takes under the obturator and prevents it absolutely from being opened by the explosion ofthe cartridge, the hammer remaining at full-cock, ready to act upon the striker'.

The mechanism also comprises a piece serving two purposes. lt is constructed as follows, see Figs. l1 and 12:) A bar, M, is applied to the external side of the breech-box, the end of which, being bent to a right angle, is prolonged into a cylindrical stem, N, traversing the breech-box above the upper branch of the mainspring. The outer bar covers the pivots of the obturator and lever, toprevent them from coming out of the box. (See Fig. 2.) At the middle ofthe stem N opposite the mainspring, is formed a notch, O. Vhen theA outer bar is placed so as to cover the pivots of the obturator and lever, the notch O in the stem. faces the mainspring, which it leaves free to act uponthe hammer. (See Figs. 2 and 3.) If the outer bar is turned, the hammer being. down, the cylindrical part of the stem replaces the notch, and, forming an eccentric, presses on the mainspring, taking the pressure of this t upon anotheraxis, and so formed and adapted that its lower part acts upon the part A3 of the obturator to open the same, and its upper part, C, acts upon the upper part, A, of the obturator, rst, to close the same against the faced end of the barrel; and, secondly, by taking under the projecting part A* thereof, to hold or lock the same firmly in position, so as to prevent it from being opened by the explosion of the cartridge, as hereinbefore described, and shown in Figs. l, 2, 3, 4, 5, and 6 of the drawings annexed.

2. The bar M, adapted to press against the outside of the breech-box for the purpose of keeping the pivots or axes of the obturator and lever in place, such bar M being provided` with a cylindrical stem, N, passing through and turning in the` breech-box above the upper branch of the mainspring, and having formed in it a notch, O, which allows the mainspring to act when the said bar M is placed so as to cover the said pivots and the notch O comes opposite the mainspring, as shown in Fig. 2, but prevents the action ofthe mainspring and sets both the hammer and its axis free when the bar M and stem N are turned round into the position shown in Fig. l, whereby the taking to pieces and putting together of the parts are facilitated, as hereinbefore described, and shown in Figs. l, 2, 3, 1l, and 12 of the draw-v ings annexed.
